Now they are telling everyone to get a password vault and they will even assign passwords that are hard to make up. I say this because your timing is right. Google store, Samsung store have password vaults. Now would be a good time to get one. Some are free. Check around.
1Password is an industrial grade password manager. It is also cross platform. I've used it for years. It will alert you if web sites that you have accounts with are compromised. It will generate strong passwords so you don't have to try and come up with passwords on the fly. I highly recommend it.
